Using this Manual

This manual is presented as an Adobe Acrobat portable document format (.pdf)

file. If you are reading this page, you have successfully installed Acrobat or

Acrobat Reader on your computer and opened this document.

The Acrobat Screen

The Acrobat screen is divided into two parts, with bookmarks on the left and

pages on the right. The bookmarks act as a Table of Contents for the manual.

Clicking on any bookmark will bring you to that portion of the manual. If a

bookmark has a triangle or plus sign to its left, this indicates that there are sub-

topics located under that bookmark. Click the triangle or plus sign to view the

sub-topics, click again to hide them.

Depending on the size of your computer’s screen, you may need to magnify the

page. You can choose the magnification you want by clicking on the

magnification box in the status bar at the bottom center of the screen.

• Fit Page shows the entire height of the page.

• Fit Width shows the entire width of the page. You won’t be able to see some of the top

or bottom of the page.

•

Fit Visible is similar to Fit Width, but shows the width of the page between margins.

You can also choose percentage views from the list, or choose Other to create

a specific percentage view. You can also use the magnifying glass button in the

tool bar to drag over an area of the page you want to enlarge.

When you change the magnification it remains at that setting for all pages until

you change it again.

Moving Through Pages

You can move forward and backward through the sections of the Elite 21

User’s Manual by dragging the vertical scroll bar. When you do this, a window

will appear showing which page you are selecting.

If you click in the background area of the vertical scroll bar, you’ll move one

page at a time. If the magnification you’ve chosen shows less than a full page,

you’ll see the top part of each page followed by the bottom part.

vii

You can also use the tool bar buttons to move from page to page.

The GCC manual also contains hyperlinks, marked by the use of Blue text

within the manual. Click on any of these links to go to that location.

Finding Text

To find specific information in the manual, use the Find command within

Acrobat. This command takes the place of a traditional index. To use Find,

follows these steps:

• Click on the Find button in the tool bar, or go to the Edit menu and select Find.

• The Find dialog box will appear. Enter the word(s) you want to find.

• Click OK. The program takes you to the next place the word appears.

• If you don’t find the information you’re looking for, press Command-G (Macintosh) or

Control-G (Windows) to Find Again. This will bring you to the next place the word appears.
